Binos mate,
This is a rumour site after all. Now I have another guess, BJ, may have even been an Audi Guest, remember the old days. Or DC or RK. Cant get the number of letters to match any others.
Mind you another pilot/V8 driver is dumb enough to have done it, but he has one more letter in his name.
Might as well let a bit slip, sooner or latter someone will know.
